« all products NEO974M H2-Sensor

Hydrogen measuring system in atmospheric air with temperature, pressure and humidity compensated signal evaluation and output via Modbus RS485/RTU or TCP (Ethernet).

Typical applications are e.g. the detection of hydrogen for room monitoring and determination of hydrogen concentrations under atmospheric conditions.

Most important properties:

  • Measuring range H2: 0 to 5 vol% H2
  • Temperature measuring range: -40 - 85 °C
  • Pressure range: 0.6 - 5 bar absolute
  • Humidity: 0-100 % r.h. (non-condensing)
  • Response time: t90 < 3 s
  • Recovery time: t10 < 3 s
  • Accuracy: ± 0.3 vol% H2 
  • Signal: Signal output via RS485 (Modbus RTU) or Ethernet with Modbus-TCP protocol 
  • Gas adapter available as screw-in version or for measuring gas in a tube
